In some undertermined circumstances, a `KeyError` might appear in:
https://github.com/odoo/odoo/blob/f9737d79e77e9abf634c8eaa4b6ea331e2aa814d/odoo/models.py#L4898-L4904
Despite the lack of reproducible use case, it seems that this was
introduced from 59b010ac36. In the meantime, other
optimizations were introduced in the prefetching of related fields, and
it seems that the fix is not necessary anymore.
Running the same script than described in
https://github.com/odoo/odoo/issues/19536#issuecomment-333118947 , we
observe the following performances:
Before the fix:
```
On change with 10 lines (10 new, 0 existing) took 0.306
On change with 20 lines (10 new, 10 existing) took 0.221
On change with 30 lines (10 new, 20 existing) took 0.208
On change with 40 lines (10 new, 30 existing) took 0.271
On change with 50 lines (10 new, 40 existing) took 0.306
On change with 60 lines (10 new, 50 existing) took 0.319
On change with 70 lines (10 new, 60 existing) took 0.354
On change with 80 lines (10 new, 70 existing) took 0.382
On change with 90 lines (10 new, 80 existing) took 0.506
On change with 100 lines (10 new, 90 existing) took 0.503
```
After the fix:
```
On change with 10 lines (10 new, 0 existing) took 0.238
On change with 20 lines (10 new, 10 existing) took 0.259
On change with 30 lines (10 new, 20 existing) took 0.250
On change with 40 lines (10 new, 30 existing) took 0.233
On change with 50 lines (10 new, 40 existing) took 0.287
On change with 60 lines (10 new, 50 existing) took 0.325
On change with 70 lines (10 new, 60 existing) took 0.345
On change with 80 lines (10 new, 70 existing) took 0.451
On change with 90 lines (10 new, 80 existing) took 0.496
On change with 100 lines (10 new, 90 existing) took 0.423
```
The fix doesn't seem to be necessary anymore, so we go back to the
previous implementation of the computed field.
